build: allow to redefine max_lcores for DPDK
In current versions of DPDK (at least as of 24.11), max
amount of cores available determined at compile_time.
Unless machine type 'native' is used, it is statically set
per platform and for most of them equals to 128.
Add a new option to allow user to redefine max amount of
lcores available to DPDK.
Type: make
